Disgusting manipulative business tactic

I have been on the Compaq package for last few months. Last month around 25 April I tried to upgrade online to premium.

After attempting online I was given message to pay R125 or so. When I checked I did not get the premium.

I called in to explain and consultant Told me that she can see on her system that it says pending she could not assist further she said that she will get a supervisor to call me back no one called me beginning of may I saw a bill for a higher amount call in again they told me the additional amount is for the premium which I had in April I told them I had no premium and I was waiting for the supervisor to call me from then

Then again I told him to please get a supervisor to sort this mess out credit that additional cost and thereafter I will pay the normal package which is dstv compact plus recording facilities consultant said she will get them to call me back again no one called me from then I've been waiting from the 1st of May when I last spoke to them no one called me and they go and cut me off disconnect me yesterday absolutely horrible service now they expect me to pay disconnection fee for day negligence when I exhausted all my 10 to sort out the matter why must I pay for what I did not receive and why must I pay a disconnection fee when they fail to call me back and sort out the matter especially when I ask a consultant on the 1st of May can I please pay the normal compact cast and then when the concert and then when the supervisor calls me then I will sort the additional premium dispute fee she told me I must not pay I must wait for the supervisor to call me back which never ever happened
